Sealing and Protection:
Multi-lip seals are installed on both the inner and outer races of the bearing. These seals are crucial for keeping out abrasive contaminants like dirt, dust, and moisture, while also retaining the essential grease lubrication. This significantly extends the bearing's service life.
Lubrication System:
The bearing is equipped with grease fittings (zerk fittings) that allow for regular and easy re-lubrication. Proper greasing is a vital maintenance task to minimize internal wear, prevent corrosion, and ensure smooth rotation over the long term.
Mounting and Pre-load:
It is securely fastened to the undercarriage and the upper frame with high-strength bolts. Proper bolt torque and pre-load are critical to maintain structural integrity and distribute operational stresses evenly across the entire bearing.
This 353-0654 slewing bearing is used for 325D 329D 329D2 330D2 excavator.
